Dependent extensions can only be made from within the UK

Is cooling period rule is applicable for my dependent as well ?
Their visa expires on 22 Mar 2017.
My wife and daughter came in london on 8th July 2016 and if they return before 8th October 2016 then also they have to wait for cooling period.

cooling off doesnt apply to dependents.
